186 HISTORY OF BRITISH ZOOPHYTES. 



by the ] st of April the head part had got a new body, seemed 

 strong and vigorous, and in no respect differed from other 

 polypes of its kind. About the same time the tail part be- 

 gan to show little tentacula, and a young polype began to

 April, new tentacula were observed round the part from

 On the 8th of April the tentacula were so much grown, that 

 they could lay hold of a worm, wliich the' polype greedily 

 devoured ; and on the 9th of April, as it seemed now com- 

 plete, he ceased to observe it and its young family. He

 soon recovered what it had lost, and the amputated part 

 grew into a perfect polype. 



His next experiment was to cut a polype lengthways into

 number of tentacula, wliich each part retained. Being
